[PATCH 13/15] thermal/drivers/samsung: acpm-tmu: Disable regmap locking for MMIO INTPEND reads

[Tudor Ambarus]

The regmap in acpm-tmu is only used for full-width 32-bit relaxed MMIO
reads of the INTPEND registers, with no read-modify-write operations or
regmap cache. Set .disable_locking = true in gs101_regmap_config to
avoid unnecessary regmap lock overhead on every INTPEND register read.
